I own a K1 750 and compared to any of my FZS600s its a fucking animal. I believe they tamed the FI gixxers down after the Y & K1 models to make them more ridable and more civilised. All I can say is that mine is a complete headbanger of a bike. I have ridden later models and they all seem to have a more extreme riding position.
